To all whom 'it may concern:

Fe it lrnown that l, Amener lemas, a subject ot' the King ot l-lungary, and a resident oi ltlewarlr, in the county ot Fssex and State oit New Jersey, have invented certain new and useitul' improvements in Valve-'Cooling Devices, ol which the following is a specication. I

. lihe present invention relates to means :tor cooling the exhaust valves ot internal oombustion engines; and has tor its main object .to utilize tor this purpose the combustible mixture as the' same enters the cylinder ot the engine. l

Another object ot' the invention is to provide a simple and ecient construction, that can be applied to engines without necessitat-v ing Amaterial changes in ythe construction thereof.

il Jturther object ot lthe invention is to so devise the cooling device that it serves at the same time as a means tor pre-heating vthe combustibile charges. l

With these and other objects in v-iew,

w ich will more `fully appear as the nature oit the invention is better understood, the same consists in the combination, arrangement and construction ot parts hereinafter described, pointed out in the appended claims and illustrated in the accompanying drawings, it being understood that many changes may be made in the size and proportion oit' the several parts and details of construction, within the scope ot the appended claims, without departing trom the spirit or sacridcing any ot the advantages of the invention.

Une oit the manypossible embodiments ot the invention is illustrated in the accom panying drawings, in whioh:--

Figure l is a vertical section taken through the combustion chamber ot an internal com bustion engine having the im roved coolin device therein; Fig. 2 is a si e elevation o" the cooling means; Fig. 3 is a top plan view thereot; and Fig. d a section taken through an improved exhaust valve-oi the engine.

ln the drawings, the numeral i0 indicates `the working cylinder of an internal combustion engine, including a `combustion chamber l1, having the usual igniting device12. rl`he chamber il is provided withl an intalre lil lor the combustible mixture, and with Ftpecitlcation ci. Letters Patent.

' valve seats, the cylinder Fatented Feb..

an 'exhaust opening la tor the products oi combustion or exhaust gases. 'Fhe intalre is controlled by a supply-valve l5 ot any suitable construction, that is disposed within a tubular body lb, communicating with the intake. This body is provided with seat 1 7 tor the supply-valve, and extends toward andterminates above the exhaust-valve it, ythat controlathe exhaust opening..

The exhaust-valve, is made in the term ot a puppet, comprising a dislr i9 and ,a stem 20. Fhe dish is provided with an upwardly extending v peripheral dange 2l, through which extend small apertures 22. e inner diameter oi the Harige 2l is substantially larger than the cuter diameter or theldownwardly directed tree end oi' the tubular body, so as not to interiore with the proper operation ot the exhaustfvalve.

lhe tubular body it is made ot two sections,ydenoted in the drawings by the nunierals 2d4 and 25, which` are detachably united by a screw 2b or other suitable means. 'lhe length ot the section 2d is such, that convenient access can be had to the ex haust-valve alter the section 25 has been detached trom the section 2d. ln registering position with the supply-valve is formed in the section 2d of the tubular body an opening 2,7, normally closed by a plug 28. 'lhe dlameter ot the opening 2l' is larger than that of the dislr l5 of the supply valve.

'lhe operation ot the cooling device is as follows-The combustible mixture enters through the intake i3 the tubular body it, ilows through the 'same and is directed by I the downwardly bent discharge end ot said `body onto the exhaust valve 18.` Fart of the ycharge is `thrown oit or bach by the disk i9 of said valve and part Hows through the apertures'22 in the dange 2l thereoi', thereby eiectively coolino" the valve.

The combustible mixture, in cooling the exhaust valve, is preheated for the wellknown, purpose. |llhe device has thus a two- :told function, towit: First, it serves as a cooler for the vexhaust-valve of the engine,

and, second, it pre-heats the fresh charge.

When it becomes necessary to re-grind the head 29 is removed from the cylinder, after which the section 25 oit' the tubular body 16 is detached from the section 24 thereof, whereby access can be ld, lidlltt.

What I claim is A 1. An internal combustion englne includ- :lng a cylinder having an intake-opening and 'an eXhaust-opening, a valve controlling said intake-opening, a valve controlling said eX- j haast-opening, each valve being provided 1'0` with a stem and the longitudinal axes of sai-d stems being spaced apart, and a tubular with a stem and the longitudinal axes ofl said stems being spaced apart, and a tubular i body communicating with said intake-opening -`andleading to and terminating above' said exhaustevalve.-

3. An internal combustion engine including a cylinder having an intake-opening and an exhaust-opening, a valve controlling said intake-opening, a valve controlling said exhaust-opening, each valve being provided with a stem' and the longitudinal axes of said stems being spaced apart, and a tubular body communicating with said intake-open ing and having-its discharge end in proximity o but spaced ,from said exhaust-valve.

4. An internal combustion engine including a cylinder` having an intake-opening and an exhaust-opening, a valve controlling said intake-opening, avalve controlling said eX- haust-opening, each valve being provided with a stem and the longitudinal axes of said stems being spaced apart, and a tubular body communicating with said intakeopening and inclosing said intake-valve and having its discharge end in proximity of but spaced from said exhaust-valve.

5. A n internal combustion engine including a cylinder having an intake-opening and an exhaust opening, a valve controlling said intake-opening, a valve controlling said exhaust-opening including a disk having-an upwardly'extending peripheral flange pro vided with apertures, and a tubular body communicating with said intake-opening and leading to and terminating above said exhaust-valve, whereby part of the charge flows through the apertures in the liange of said eXhaust-valve- 6. An internal combustion engine including a cylinder having an intake-opening and an exhaust-opening, a valve controlling said intake-opening, a valve controlling said exhaust opening including a disk having an upwardly extending peripheral ange provided with apertures, and a tubular body commiinicating with said intake-opening inclosing said intake-valve and leading to and terminating above said exhaust-valve, whereby part of the charge flows through the apertures in the flange of said exhaustvalve.
